PUMPING APPARATUS.

Application filed August 23, 1922. Serial No. 583,836.

T 0 all whom it may concern:

Be it known that 1,.HENRY H. SMITH, a citizen of the United States,residing at Cherryvale, in the county of San Miguel and State of NewMexico, have invented certain new and useful Improvements in PumpingApparatus, of which the following is a specification, referencebeing-had to the accompanying drawings.

This invention relates to improvements in pumping apparatus and moreparticularly to means for connecting two way pumps to a windmill.

A further object of the invention is to provide means whereby aplurality of rods may be operated from a swivel head wind mill and atthe sametime permit rotation of the head of the windmill to face intothe wind without twisting the operating rods.

A still further object of the invention is to provide a device of thischaracter which is simple in its construction and arrange ment and whichmay be readily applied to the pump rods of a two way pump.

These and other objects I accomplish by the construction and arrangementshown in the accompanying drawingswherein for the purpose ofillustration is shown a preferred embodiment of my invention and whereinlike reference characters designate like parts throughout,

In the drawings Figure 1 is a sectional view showing a pumping apparatusconstructed in accordance with my invention;

Figure 2 is a section on the line 22 of Figure 1; and Figure 3 is atransverse sectional view showing the connection of the pump rods to theoperating rods thereof.

Referring now more particularly to the drawings, the numeral 10designates a pump of the type generally known in the trade as a two waypump, 11 the pump barrel and 12 and 13 the lower and upper pump valvesrespectively, both of which comprise a piston having an upwardly openingcheck valve 14: therein. Each of the pistons 12 and 13 has a close fitwithin the cylinder 11 and in the operation of the pump these pistonsare oppositely reciprocated so that they move mutually toward oneanother or away from one another. The operating rods for the pistons 12and 13 comprise a solid rod 15 secured to the lower piston and a tubularrod 16 secured to the upper piston and through which the rod 15 of thelower piston extends. The numeral 17 designates the swivel head of awindmill of any desired construction and 18 a shaft driven from the windwheel 19. The shaft 18 embodies a pair of cranks 20 and 21. These cranksoperate connecting rods 22 and 23 respectively, having at their lowerends cross heads 24 by means of which they are connected to pumping rods25 and 26. The pumping rod 25 has an offset 27 extending over the upperend of the stem 15 and provided with a swivel 28 by means of which it isconnected to the stem 15. The rod 26 is provided with an offset 29having at its end a swivel collar 30 adapted to be secured to, the upperend of the tubular stem 16. In connecting the pump and swivel head ofthe wind-mill, the same are preferably arranged so that the connectingrods 22 and 23 are arranged upon opposite sides of the ,aXial center ofthe stems 15 and 16 and equidistantly spaced therefrom. Upon rotation ofthe head, as the wheel is forced into the wind, the swivels connectingthe pump rods 25 and 26 to the stems 15 and 16 will permit relativerotation of the head and stems 15 and 16 and accordingly will preventstrain being placed upon the connecting rods and twisting of the pumprods. The swivel head of the windmill is preferably mounted upon theupper end of a casting 31 having guides 32 in which the cross heads 24-operate, this casting rotating as a unit with the head 17 and havingformed at its upper end bearings 33 in which the shaft 18 operates.

From. the foregoing it is believed to be obvious that a pump connectionconstructed. in accordance with my invention is particularly welladapted for the purpose for which it is intended for the reason that itpermits the use of windmill for operating a two way pump without dangerof strain being placed upon the bearings and pump rods which tend totwist the same. It will furthermore be obvious that the construction ashereinbefore setrfortb is capable of some change and modificationwithout materially departing from the spirit of my invention and Iaccordingly do not limit myself to the specific structure hereinbeforeset forth except as hereinafter claimed.

1 claim w 1. The combination with a pump embodying a barrel, upper andlower pistons opersting, within the barrel, the upper piston having atubular stem and the lower piston having a stem extending upwardlythrough the tubular sternol the upper piston, and a swivel head windmillembodying a drive shaft provided with cranks, of pump rods having swivelconnection with the stems of said pistons, connecting rods Connectingthepump rods with said cranks, and a connection between the windmill headand pump rodsn aintaining fixed axial relation therebetween.

2. The combination with a pump embodying a barrel, upper and lowerpistons operating" within the barrel, the upper piston havinga tubularstem and the lower piston having a stem extendingupwardly through thetubular stem of the upper piston, and a swivel head windmill embodying adrive shalt providedwith cranks, of pump rods having swivel connectionwith the stems of. said pistons, connecting rods connecting the pumprods with said cranks, each of said connecting rods being provided withor cross head, and e holloweesting secured to and rotating; with theswivel head of the windmill and provided interiorly with guides for saidcross heads.

In testimony whereof I'hereunto- :iflix my signature.
